The width (w) of the fluid inlet (18) is greater than that (d) of the controlling part (14) but less than that (D) of the main part (13). The yarn (17) is guided to run in the yarn controlling part (14) which the fluid inlet (18) intersects and the fluid is directed past the running yarn (17) in the direction of the main part (13). The yarn guides (15, 16) are movable toward and away from the inlet and outlet ends of the yarn passage (12). A curved threading slot (19) connects the controlling part (14) with the outside of the jet (10).

Title: Laser segmentation of plated through-hole sidewalls to form multiple conductors
Inventor: JAPP ROBERT M
IPC: H05K3/00
Filed: 2000-03-14
Granted: 2002-10-11
Abstract: A method for generating multiple conductor segments within a plated through hole of a printed circuit board. The method utilizes laser light to define the segmented surfaces bounding a hole in a circuit board. Two embodiments of this method are a subtractive process and an additive process. The subtractive process starts with a plated through hole and uses a laser to removes vertical strips of the PTH conductive lining to form the multiple conductive segments. The additive process applies a seeding material to a bare hole in a circuit board, removes vertical strips of the seeding material via laser scanning, and applies an electrically conductive material to the seeded surfaces to form the multiple conductive segments.

Title: Titanium-containing silica glass honeycomb structure from silica soot extrusion
Inventor: HRDINA KENNETH E
IPC: C03B23/047
Filed: 2000-04-11
Granted: 2002-06-11
Abstract: The present invention describes an extrusion process for manufacturing a titanium-containing silicate glass honeycomb structure, having a variety of shapes and sizes depending on its ultimate application. The titanium-containing glass honeycomb have a very low coefficient of thermal expansion (CTE) and the CTE can be varied by adjusting the titanium level to match the CTE of members that are bonded to the honeycomb. Furthermore, the inventive honeycomb structure is lightweight, yet able to support heavy loads on its end faces. Therefore, the inventive honeycomb can be advantageously used as a light-weight support for such objects as mirrors. Especially contemplated is using these inventive honeycomb supports for mirrors used in extraterrestrial environments where temperature extremes are present. These honeycombs can be used singularly or in aggregates to provide such support. Embodiments are described wherein the mass of the honeycomb is further reduced by removing select portions of the honeycomb without deleteriously impacting its ability for load bearing.

Title: Fabricating process of thin ball grid array substrate
Inventor: SHIE WEN-LE
IPC: H01L21/00
Filed: 2000-05-04
Granted: 2001-07-01
Abstract: This invention is about the fabricating process of thin ball grid array substrate. In this invention, a thin copper surface layer is first sputtered on a polyimide film and is followed by electroplating a thicker copper layer on the copper surface layer. After that, the thicker copper layer is covered with a photosensitive coating, which is then separated by an appropriately treated mask (having the disposed circuit track) so as to be irradiated and underexposed. Therefore, the corresponding position on the photosensitive coating layer with respect to the circuit track of mask is etched away so as to form a circuit track of photosensitive coating that is recessed to copper layer. The manner of electroplating is used to make the thickness of copper circuit track become thicker. Substrate that is not protected by the bottom photosensitive coating is etched away. Metal material (such as lead tin alloy 63Sn/37Pb) is electroplated inside the recessed track of the front photosensitive coating. After removing the photosensitive coating and etching away the excess copper route, the process is completed.

Abstract: A method and system is disclosed for dynamically routing a material transport vehicle using traffic based parameters. A controller directed to allocate a material transport vehicle to a particular node, selects the material transport vehicle that is physically closest to the particular node. The controller calculates an optimal route by identifying the possible routes between the initial node of the material transport vehicle and the destination node, and analyzing each of the nodes within each identified route according to a metric function by calculating a metric function value for each identified route. The controller then selects the route for the material transport vehicle having the smallest metric function value. The metric function may include parameters associated with each of the nodes in the material transport system including a node-to-node distance parameter, a node crossing parameter, and the number of material transport vehicles in a queue at each node within the route. In one embodiment, the metric function is given by formula.

Title: Method for preparation of polycarbonates
Inventor: SEOANE CARLOS GODINEZ
IPC: G11B7/253
Filed: 2000-10-31
Granted: 2006-02-11
Abstract: A method is provided for the preparation of polycarbonates by the reaction of a diaryl carbonate, such as DPC and a dihydric phenol, such as BPA. The method utilizes the steps of successively processing the diaryl carbonate and the dihydric phenol in a melt in a first reaction stage, a second reaction stage and at least a first polymerization stage, and shifts the processing conditions such that the desired low viscosity/high end-cap product is obtained. This is achieved by having the ratio of diaryl carbonate to dihydric phenol in the melt prior to the first reaction stage greater than 1.08; and by controlling the temperature and residence time in the first polymerization stage to provide a polycarbonate product having a melt flow rate at 250 DEG C of greater than 10 g/min and an end-cap level of at least 90%. The method of the invention can be used in a linear manufacturing process, in which there is one product produced. The method of the invention can also be incorporated into a multi-line manufacturing process for the simultaneous production of more than one product. Thus, a stream of product produced from the first polymerization stage may be split into two or more lines which are further processed to produce, for example, a low viscosity, high end-cap product and a medium viscosity, moderate end-cap product.

Title: MOS-transistor and drive-circuit with such a MOS-transistor
Inventor: WERNER CHRISTOPH
IPC: H01L29/06
Filed: 2000-11-10
Granted: 2002-08-11
Abstract: The MOS-transistor has a current-limiting element (E1), which is arranged between a source-region (S1) and a drain-region (D1) and adjacent on a gate-dielectric (GD1) and on a channel-region (KA1) of the MOS-transistor. The current-limiting element (E1) extends with a part to such a distance from the gate-electrode (GA1), so that during the control of the gate-electrode (GA1) no inversion-layer is formed on this part. The current-limiting element (E1) is constructed so that at least one part of the charge-carriers, which flows during the control of the gate-electrode (GA1) from the source-region (S1) to the drain-region (D1), move across a part of the channel-region (KA1) in the area of the part of the current-limiting element (E1), on which no inversion-layer is formed. The current through the MOS-transistor is especially small in a small voltage-drop due to the current-limiting element (E1), while this current in a higher voltage-drop, in which the charge-carriers move from the inversion-layer through injection before arriving the current-limiting element (E1), hardly smaller than that in a MOS-transistor without current-limiting element (E1).

Title: Deposition of gate stacks including silicon germanium layers
Inventor: MANSOORI MAJIID M
IPC: H01L21/28
Filed: 2001-02-12
Granted: 2002-02-21
Abstract: Methods and structures are provided for forming silicon germanium gate electrodes over gate dielectrics. A thin polysilicon wetting layer provides continuous coverage of the silicon dioxide layer and reduces incubation time for the silicon germanium thereupon. The continuity of the wetting layer leads to a uniformly thick, planar gate electrode structure. At the same time, the polysilicon layer can be made thin enough to minimize thermal requirements for segregating germanium to the electrode-oxide interface, and providing grain boundary diffusion to further facilitate germanium diffusion. Advantageously, the polysilicon wetting layer, silicon germanium and a further silicon cap layer are all formed in situ under atmospheric pressures.
